ELECTRICALLY-HEATED HANDHOLD.

SPECIFICATION f rm g p of Letters Patent 795,201, dated July 18, 1905.

To all 1071/0711, it may concern:

Be it known that I, FRED SMITH DAvIs, acitizen of the United States, residing at Robertsville, in the county of Hampton and State of South Carolina, have invented certain new and useful Improvements in Electrically-Heated Handholds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in electrically-heated handholds; and the object of my-invention is to provide for an operator who is exposed to the cold an electricallyheated handholdsuch, for example, as rheostat and brake handles on electric motor-cars or electric automobiles, pilot-wheel handles on boats or ships, and brake-handles on railway-cars.

The object of my invention is to do away with the ordinary handles of wood or metal and to substitute in their place a handhold electrically heated at the will of the operator to such a temperature that will insure the operator having his hands comfortable even in the severest weather. Furthermore, as the palm of the hand is a large nerve-center, such an electrically-heated handhold will aid materially in keeping the operator warm.

In the accompanying drawings, Figure 1 shows a brake-lever with my improved handhold applied thereto, the latter being shown in cross-section; and Fig. 2 represents a pilotwheel having my invention applied thereto.

(0 represents the brake-lever, which is provided with a handle I), which is hollowed out, as shown at c.

represents a screw-threaded plug into whichis screwed an electric lamp 0 of the required size to keep the handle Z) warm. Of course instead of the electric lamp 0 any electric heating means may be usedsuch, for example, as an ordinary heating resistance-coil. The top of the handle 0 is hermetically closed by the screw-threaded plug 6, so that the heat of the lamp or resistance-coil will be all given up to the handle 6.

f represents a pair of wrapped insulated wires running down through the handle and along the lever a, preferably in a groove therein, to any source of electric supply.

g represents an insulating-plug, and I2, represents a contact-plug which can be inserted or removed at the will of the operator.

In Fig. 2, 71 represents a pilot-wheel provided with handles 1', in each of which is located an electric lamp or resistance-coil k. Z represents electric wires running from said lamps to a central plate m, which is provided with a contact-plug 42 similar to the one shown in Fig. 1.

It is obvious that by inserting the plugs or a an electric current will be caused to flow through the lamps or resistance-coils in the handles 6 or 1', thereby heating them, thus adding greatly to the comfort and health of the operator. T

I prefer to make the handles 5 and j of metal in order that the heat may be more readily conducted through them.

Having thus described my invention, what I claim as new is 1. The combination of a handle, electric means therein for heating said handle, electrical conductors leading to said means, and a removable contact-plug, substantially as described.

2. The combination of a handle provided with a hollowed-out portion, electrically-operated means located in said hollowed-out portion for heating said handle, a plug for hermetically closing said handle, insulated electric wires leading to said; heating means, an insulating-plug breaking the circuit through said wires, and a contact-plug adapted to be inserted in said insulating-plug to complete the circuit, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
